Abstract: 937,637. Travelling-wave tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 2, 1962 [Feb. 7, 1961], No. 4112/62. Class 39 (1). A travelling-wave tube having a helical slowwave structure 9, insulating support rods 10 extending along and supporting the slow-wave structure, the ends of the structure being coupled to input and output waveguides 1, 2, comprises between the ends of the helical structure a disc-shaped conductor 11 extending through the wall of the tube so as-to connect on the outside of the tube with a cylindrical metal wall 4 of a mounting system and which supports a conductive tube 12 closely surrounding the helical structure and insulating support rods, the tube extending with the envelope of the travelling-wave tube for a distance of between a half and three-quarters of the length of the slow-wave structure. The tube 12 is preferably of nickel-copper and may be supported by the disc 11 placed at the mid-point of the travelling- wave tube and electrically connected to the waveguide supporting structure 4. The envelope 5 is supported within the tube 4 by annular springs 14, 15 and 18. It is stated that the provision of the conductive tube 12 prevents parasitic modes of oscillation between the input and the output and is effective over a larger frequency range than prior art devices.

Abstract: 347,347. Combined sound record and kinematograph films. NAAMLOOZE VENNOOTSCHAP KœCHENMEISTER'S INTERNATIONALE MAATSCHAPPIJ VOOR SPREKENDE FILMS, AMSTERDAM-BERLIN, 43, Mauerstrasse, Berlin. Feb. 11, 1930, No. 4571. Convention date, Feb. 12, 1929. [Class 40 (ii).] Relates to the production of sound and picture image films. The recording of the sounds is effected on an intermediate record carrier such as a magnetic wire, strip, or the like which is moved synchronously with the picture record film. This sound record is then transferred photographically to a zone left free on the negative image film at such a reduced speed that sufficient exposure of the film for the sound record is ensured. The sound and image records thus photographed upon a single film can be developed together. The photographing of the image record is accomplished by covering or designing the optical device so as to leave a space on the film free for the reception of the sound record. The manifolding of the film may be effected by first printing the picture images only, the film being moved forward each time in jerks by the length of one image, while the subsequent printing of the sound record is effected at uniform speed. Alternatively, the image and sound records may be printed simultaneously by a uniform movement of the film past the printing light.

Abstract: 565,100. stuffing-boxes. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, W. H. J. March 20, 1943, No. 4571. [Class 122 (v)] [Also in Group XXII] Relates to the fixing of transverse partitions in cylindrical bores and consists in expanding a flange originally parallel to the axis into a groove in the wall of the bore. The expansion may be effected by inserting and flatten- 'ing a dished washer which may remain in the partition member to reinforce the flange. As applied to sealing the driving shaft 15, Fig. 1, in a pump casing the groove 21 is of V-shape with its walls at right angles, one wall 22 being inclined to the axis at an angle greater than 60 degrees. The member 18 with its flange 20 originally parallel to the axis is inserted to abut the outer race 12 of the ball bearing being recessed to clear the inner race. A peripheral groove contains a roller &c. packing ring 25 and the flange is upset to the position shown in which the .wall 22 forms an efficient abutment preventing removal of the member. A recessed packing washer 16 is fitted to form a seal round the shaft. A gland packing 52, Fig. 6, for a piston-rod may be secured by a flanged member 53 expanded by flattening a dished washer 56 which may be resilient to resume its dished position, on removal of the flattening punch 57, and facilitate removal.

Abstract: 976,194. Paper-making. BELOIT IRON WORKS. Feb. 7, 1961 [April 4, 1960], No. 4577/61. Heading D2A. An uncoated paper web, which is plasticizable by heat and pressure, is gloss-finished by drying it to a moisture content of less than 35% and immediately thereafter passing it through a nip between two rolls. The first roll is heated to a temperature sufficient to plasticize the fibres of the web in contact with it, and has a smooth surface harder than the cover of the second roll. The second roll comprises a core and an outer deformable and resilient cover having a hardness of less than 30 P and J (<SP>1</SP>/ 8  inch ball). The two rolls are forced together with sufficient pressure to coalesce the plasticized fibres. As shown, paper from a Fourdrinier machine is passed through wet-presses (not shown), and then through a first drier section 63A to bring the moisture content to less than 35%. It is then surface-glossed on each side by being pressed between, on the one hand metal rolls 33 and 51 with smooth surfaces plated with chromium or nickel and internally heated, and on the other hand rolls 34, 35, 52 and 53 with metal cores and resilient cores of the required hardness. The rolls are forced together by the bellows 36. Drying is continued in a further drier section 63B, and the paper is again pressed by further sets of rolls 12A, 13A, 14A and 12B, 13B, 14B before being reeled up at 66a, or coated at 67, dried at 68, further glossed at 69 and fed to a reel (not shown). The length of each nip, in the machine direction, is preferably less than one inch. In another embodiment (Fig. 4, not shown), the web passes round fly-rolls between the two nips of each press.

The calculator may be in disc form (as shown) or in slide rule or cylindrical form. In the preferred form the member 14 overlies the third scale 22 and is scalloped at the edge to reduce wear.
